Expression of stress- responsive genes in SaSce9 Arabidopsis plants. Relative mRNA levels of stress-responsive genes were determined by quantitative RT-PCR using cDNA synthesized from total RNAs isolated from the shoots of 3-week-old Arabidopsis plants grown under normal conditions in soil. The Arabidopsis tubulin gene was used as an internal control for normalization of different cDNA samples. Error bars represent standard error of means based on three independent reactions.
